TUNIS — One of Tunisia's most wanted militants and a top field commander for the Islamic State group died fighting in Libya, the Tunisian government confirmed on Tuesday. The Islamic State group posted a eulogy on a militant website for Ahmed Al-Rouissi after he was killed in clashes around the Libyan city of Sirte — a stronghold for the Islamic State affiliate. Tunisian Interior Ministry spokesman Mohammed Ali Aroui told the state news agency that al-Rouissi's death had been confirmed through “scientific means” and in coordination with Libyan authorities. There has been fighting around Sirte between IS militants and the Misrata-based 166th Battalion, which is loyal to the Libyan government in Tripoli. Libya's internationally recognized parliament has been forced from the capital and meets in the eastern city of Tobruk. It is currently in talks with its Tripoli-based rival about forming a national unity government. — AP
